THE OBSERVED EVIDENCE
What changed after the flow was redesigned?
The comparison below separates what was observed before the intervention from what was observed after the flow redesign. The same installed asset increased its average production without a conventional capacity-expansion project. This case does not imply that every asset will reproduce the same result.
OBSERVED AFTER
Average production
12,047 tonnes/day
Improvement in average: 25%
Gap to demonstrated capacity: approximately 15%
Budget shortfall reduced from 3,388 to 953 tonnes/day: 72%
Final position: 7.3% below budget
OBSERVED BEFORE
Average production
9,612 tonnes/day
Best three days: 14,136 tonnes/day
Budget: 13,000 tonnes/day
Gap to demonstrated capacity: 32%
THE OPERATING QUESTION
Why was demonstrated capability not reaching the point of sale?
The asset was missing budget, yet its best repeatable days showed that the installed system had already produced well above the average. The question was not whether every lost tonne could be recovered. It was why demonstrated capability was not reaching the point of sale predictably.
Observed data, intervention, outcome and limits
1 — THE EVIDENCE
Average production was 9,612 tonnes/day. The best three days averaged 14,136 tonnes/day against a budget of 13,000 tonnes/day. This revealed a 32% gap between the operating average and demonstrated capacity.
2 — THE INTERVENTION
The work focused on the stable system constraint, the flow of work into and through it, the protective capacity and buffers required to keep it productive, and the local decisions that repeatedly interrupted system output.
3 — THE OUTCOME
After the flow redesign, average production reached 12,047 tonnes/day: a 25% improvement without conventional capacity expansion. The budget shortfall reduced from 3,388 to 953 tonnes/day, leaving the operation within 7.3% of budget.
4 — WHAT THE CASE DOES NOT PROVE
This case does not prove that the whole best-day gap was recoverable, or that additional sustaining expenditure will not be necessary. It demonstrates why repeatable capability and constraint behaviour should be investigated before approving conventional expansion.
